The Indian Ocean is the third largest of the world’s oceans, and covers approximately 20% of the water on the Earth’s surface.  The Indian Ocean is the warmest ocean in the world. With Zanzibar being close to the equator, water temperatures do not vary much – the year average is 27C, with a maximum of 31C and a minimum of 25C.
A diving paradise in East Africa, Zanzibar has a wealth of varied dive sites with different topography and conditions. There are sites with wall diving, continuous reefs, jigsaw-esque coral bommies, and of course there are the historical wrecks in Stone Town. There is something for every skill level of diver – from the first time beginner, to the seasoned advanced level diver.
As is almost always the case with diving, maximum depths vary with location, and the visibility around the island can reach up to 50 metres. The conditions on the west coast tend to be a little more calm – which is ideally suited to beginners, and on the east coast the surface conditions and currents can test more skilled divers.
In terms of marine life around the dive sites of Zanzibar you will always find a myriad of tropical reef fish, blue spotted rays, moray and ribbon eels, and other regularly seen species include octopus, barracuda, green turtles and hawksbill turtles. For some lucky divers they also get to see white-tipped and black-tipped reef sharks, and the whale-shark migration season runs from September until the end of the year.
The diving around Zanzibar is also a fantastic area for macro photographers – various nudibranchs, pipefish and whip gobies can be found by those with a keen eye for the smaller stuff.


On the east coast of Zanzibar lies the idyllic Mnemba island. This small, privately owned island is surrounded by a large circular reef. In the clear turquoise waters surrounding this marine conservation area, a great diversity of marine life can be found. Bottlenose dolphins often visit the waters around the island and green turtles lay their eggs on its white beaches. From July till September, humpback whales cruise through the waters near Mnemba island. There are many beautiful dive sites around Mnemba and it is a popular area for both scuba diving and snorkeling.
